Rename the "async" ioctl API to "unlocked" so that upcoming usage in x86's TDX code doesn't result in a massive misnomer. To avoid having to retry SEAMCALLs, TDX needs to acquire kvm->lock *and* all vcpu->mutex locks, and acquiring all of those locks after/inside the current vCPU's mutex is a non-starter. However, TDX also needs to acquire the vCPU's mutex and load the vCPU, i.e. the handling is very much not async to the vCPU. No functional change intended.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
